NOISE COMPENSATOR OF BOC TYPE Russian patent published in 2020 - IPC H04B1/10 

FIELD: navigation systems.

SUBSTANCE: invention relates to radio equipment and can be used in receivers of global navigation satellite systems using broadband signals with modulation at subcarrier frequencies (in the English-language literature the term BOC-signals is used), which are installed both on slow-moving objects, and on objects with high dynamics. Noise compensator of the BOC type comprises a subtractor, an adder, N channels for generating a copy of noise, having a first multiplier, a second multiplier, an amplitude meter, a phase tracking system, a third multiplier, an interference detector, a delay monitoring system and a noise copy generator, as well as a fourth multiplier, a fifth multiplier, a sixth multiplier, a seventh multiplier and a meander tracking device for interference.

EFFECT: reduced level of power of signal-like phase-shift keyed interference with binary modulation at subcarrier frequencies due to reproduction of "copy" of this noise, taking into account delay time and further subtraction of "copy" of noise from input signal-interference mixture.
